The number oi' individual pens assembled in a single barrel is not limited, and two or four individual pens may be so combined. One or more fountain pens may be replaced by ordinary nonilling pens or pencils, the cross section of which resembles that of the fountainv pen or pens combined with it. A pencil of this kind is illustrated portions, provided that they are always irmlyv seated in the barrel;

It is wished to be understood that it is not desired to be limited to the exact details of construction shown and described for obvious modications will occur to a person skilled in the art.

What is claimed is 1. A multiple fountain pen comprising in com bination, a barrel, a plurality of individual fountain pen holders assembled in said barrel for individual longitudinal displacement in frictional contact with each other, a pen in each pen holder, the ends, carrying the pens, of all pen 2,144,oss

holders, when in inoperative position, projecting suiiiciently from said barrel to allow being individually gripped and advanced into writing position.

2. The multiple fountain pen of claim 1, in which a stop is formed on the projecting part oi' each pen holder, said stop extending radially across the edge of the barrel so as to prevent the holder from being pushed farther into the barrel.

3. A multiple fountain pen comprising in combination, a barrel, a plurality of individual fountain pen holders in said barrel, all projecting substantially uniformly from said barrel, the projecting portion of each holder being formed with a stop, a sleeve forming part of each holder extending into the barrel, the sleeves of the individual fountain pens having cross sections such as to completely ll together the inner cross section of said barrel, a compressible sac forming part oi' each individual fountain pen, and a prong-like compressing means embracing said sac and projecting from the rear end of said sleeve. one end of said compressing means being ixed to said sleeve.
